About the role

We are seeking a highly skilled Senior Platform Engineer – GitHub DevOps & Cloud Automation to design and build scalable, self-service platform capabilities that accelerate software delivery, improve developer productivity, and reduce operational overhead. This role focuses on modern platform engineering practices, GitHub-based DevOps automation, Kubernetes platforms, Infrastructure as Code, CI/CD modernization, and cloud-native engineering.

You will architect and implement resilient infrastructure solutions, developer self-service capabilities, GitOps workflows, and AI-driven operational tooling that enable large-scale enterprise application delivery across hybrid and cloud environments.

In this role, you will:

• Design and build self-service platform capabilities that enable engineering teams to provision and manage infrastructure with minimal operational support.


• Architect and implement GitHub Enterprise-based DevOps platforms, repository standards, branching strategies, and governance models.


• Develop and maintain enterprise CI/CD solutions using GitHub Actions, GitOps, and Infrastructure as Code practices.


• Create reusable platform components, templates, and automation workflows that standardize infrastructure provisioning and application deployments.


• Build scalable Kubernetes-based platforms across cloud environments, including Amazon EKS and related ecosystem technologies.


• Automate infrastructure lifecycle management using Terraform and cloud-native services.


• Drive platform reliability through observability solutions leveraging tools such as Datadog, Prometheus, and Grafana.


• Collaborate with development, operations, and security teams to implement DevSecOps practices, policy automation, and compliance controls.


• Design disaster recovery, backup, and resilience strategies for mission-critical platforms.


• Implement GitOps deployment models using tools such as ArgoCD to improve deployment consistency and operational efficiency.


• Evaluate and implement AI-powered platform engineering solutions using technologies such as RAG, AWS Bedrock, OpenSearch, and related frameworks to improve developer experience and operational productivity.


• Analyze deployment metrics, platform health indicators, and infrastructure utilization data to drive continuous improvement and cost optimization.


• Support incident management, root-cause analysis, and platform modernization initiatives across enterprise environments.


• Provide technical leadership, mentoring, and architectural guidance to engineering teams.
